If there's one thing I don't want Milo to be, it's a Gary Stu. (For those of you aren't familar with the term, a "Gary Stu" is basically a male version of a Mary Sue. Maybe that's why the two terms rhyme? XD)

Anyway, I know being nice isn't synonymous with being "obssessively perfect to a fault" (heck, look at Arnold and even Lila). However, I want show a little snarkiness in the little kid...just to deepen his character.

Disclaimer, right. (Clears throat) I do not own Hey Arnold! All its elements, including the characters, belong to Craig Barlett. All OCs, however, belong to me.

Harold

"Hey, Arnold, what's with the little kid? We came here to play baseball, not babysit some snotnose brat."

Arnold and Milo were currently standing on the edge of Gerald Field, the game being set for the afternoon.

Our football-headed hero could only mutter warningly in annoyance,

"Harold…"

This was why Arnold was dead set against bringing Milo here. The second-grader could handle Oskar's complaints, he could take Grandpa's teasing, and Arnold swore he could even handle Helga's sarcasm.

Only one problem: those were all people Milo was used to.

Harold wasn't one of them, so Arnold wasn't sure how the 7-year old would respond.

Bonnie could've have come as moral support (physical even if the situation had called for such) but she was stuck working double overtime at the public library.

"Ignore him. Harold's always saying a bunch of stuff he doesn't mean."

Arnold just hoped the younger kid wouldn't react with the same temper that his mother was well known for.

There was already enough steam with Helga and Harold on the field.

Much to Arnold's surprise, Milo gave a snort.

"Nah, don't sweat it, Arnold," the younger boy replied.

He motioned his index finger to have Arnold lean down so their heads were level.

"That guy," Milo whispered clandestinely in Arnold's ear, "he's just ticked at me 'cuz of this race we had yesterday."

"Really?"

Milo nodded and led Arnold to the benches before he continued with his words.

"Yeah, I got to the prize minutes before he could."

"And… what was the prize?" asked Milo's "big brother" reluctantly.

Knowing Milo, Arnold was a tad worried about what had been at stake.

"Oh, just a chocolate bar, nothing big. He pouted and grumbled a bit about losing, but that's not what's got him acting so sour today."

The wise football-head sure hoped that his unofficial little brother had shown good sportsmanship. He crossed his arms, giving himself a heavy air of sternness.

"Then why is Harold so upset with you?"

Milo must have noticed the suspicion in Arnold's tone because he quickly held up his hands in defense.

"Easy there. I all did was give the big lug half of the chocolate, you know, to show there were no hard feelings."

Wait…what?

"And … Harold got upset over that?"

Okay, now Arnold was only getting confused.

"Sure did," confirmed the dark-skinned boy with a nod.

"He said, and I quote,"

Puffing up his cheeks, pouting his lips, and then forming a scowl on his face, Milo proceeded with his imitation of a certain "Pink Boy."

"'Hey you're not supposed be at all nice when you win!'"

Okay, Arnold had to admit. He was pretty impressed with Milo's impersonation abilities. The kid sounded almost like Harold—not perfect but definitely close.

"Uh…I'm not?" Milo continued, now acting out the aftermath of yesterday's race.

"Course not! You're supposed to rub it in my face. That's what winners do!"

Arnold could only do a facepalm and sigh.

Yep, typical Harold…

Speaking of which…

"Hey Arnold! How much longer are you gonna have to babysit? We got a game here."

Both boys immediately turned their heads towards the source, not that they needed to be reminded of who the source obviously was.

Harold was impatiently tapping his foot, his arms crossed and a scowl not too dissimilar from that of Milo's impression.

Arnold resisted the urge to roll his eyes.

Milo resisted the urge to smirk devilishly.

'Oh, I'm a baby, eh? Well then, this 'baby' will just have to put you back in your place, won't he?'

Yep, Harold is in for it now! And unless you want to join him, I suggest you review. ;)
